Replacing Your Ductwork — Is It Time?

Replacing Your Ductwork — Is It Time?The ductwork that distributes conditioned air throughout your home plays a vital role in how well your heating and cooling system performs. If the ducts are in poor shape and need to be replaced, various problems can develop such as:

  • Hot or cold spots and difficulty maintaining a consistent temperature between rooms.
  • Excessive dust and a decline in air quality caused by contaminants drawn in through leaks or disconnected sections.
  • Moisture buildup in ducts that allows mold to flourish inside the HVAC system.
  • A loss of efficiency and unnecessarily high energy bills.

How to Assess the Condition of Your Duct System

If you’re experiencing any of the above issues and suspect decaying ductwork is the culprit, there are some steps you can take to help determine if it’s due for replacement:

  • Consider the ductwork’s age and quality. If the duct system was poorly designed, not made of quality materials, or improperly installed, the joints and seams can start to deteriorate in just 10 or 15 years.
  • Examine exposed ducts in the crawl space, garage and attic. Look for gaps around the joints, disconnected sections, dust streaks radiating out from the seams, and signs of corrosion or rust.
  • Check for temperature variations and reduced airflow. Lower air volume at the registers in certain rooms points to hidden ductwork problems like collapsed or disconnected sections. Hot or cold spots can indicate issues with decaying sealant and missing or poorly-installed insulation.
  • Have a blower test performed. A trained technician can calculate how much leakage is occurring by pressurizing the ducts and measuring the amount of airflow it takes to maintain the pressure level.
  • Schedule a professional inspection. An experienced HVAC contractor can perform a thorough inspection to assess the condition of your ducting. If replacement is recommended, the new duct system should be designed and sized correctly and properly installed, sealed, and insulated. After it’s in place, a reliable contractor will test the system for leaks and air quality.
